Abstraction Pack 3.7a

The Abstraction Pack is a level pack containing 20 levels spread across 4 cups. These tracks occupy MAPGA-MAPGF, MAPGH-MAPGP, MAPZG-ZH and MAPZK-ZM. The maps also have Record Attack ghosts for practice. If some maps prove to be unsuitable for usage, use AbstractReduction.soc to trim this pack to down to 6 maps and hide the other ones. You are also able to use custom, external SOCs for this purpose (or any others), but you accept any risks for doing so.

The Stargazer Cup is a set of difficult courses about staring into the night sky and ascending to space. The courses are based off of previous levels that I have made.

Overgrown Castle (Map GA): A miniaturized, theme park version of a castle overrun with weeds and gnarled roots. This 3-lap beginner course has consistent road widths and basic drifts. The only punishment for failure is the off-road. This course should take 2:15 to 2:30 to complete.

Midnight Caves (Map GB): Traverse a cave network which loops in on itself and the adjoining mountain sides. This 3-lap beginner/intermediate course has many turns and falls to look out for. This course should take 2:00 to 2:30 to complete.

Empty Sanctum (Map GC): A long abandoned sanctuary of mysterious purposes. Eggman has taken some claim to the areas he could reach. This 3-lap intermediate course has pitfalls and steep turns. Knowing about drift storage while airborne can save some time on this track. This track should take 2:30 to 2:45 to complete.

Bio Satellite (Map GD): A turbocharged orbital conservatory with lasers to carve the landscape and stop intruders. This 2-lap intermediate/expert course has some daring turns and drifts. The lasers will change your racing line both laps. There are 3 shortcuts in this stage, with 2 not being as obvious. This track should take 2:00 to 2:45 to complete.

Cosmic Rift (Map GE): The final course in the Stargazer Cup. Traverse solidified planetoid rings with nothing but boosters and signs to keep you company. This 3-lap expert course has no off-road nor walls to keep you safe. The road is consistent and somewhat wider to compensate. Break drifting may be needed for steep or tight turns. This track should take 2:00 to 3:00 to complete.

The Dreamweaver Cup is a set of courses about the fantastic realms available if the mind is allowed to wander. Even though it takes place after the Stargazer Cup, it is much easier than it.

Ethereal Crystal (Map GF): A set of landmasses in another plane of existence populated by mountains and floating objects made entirely of crystal. The trees in this realm are of an unknown nature and purpose. This 4-lap beginner/intermediate course has some pits and tight turns worry about, but it should be no challenge after Bio Satellite and Empty Sanctum. This course should take 1:50 to 2:20 to complete.

Sublime Bastion(Map GH): A pure realm of eternal festivities. The wide road and easy turns ensure anyone can join in on the fun. This course should take 1:45 to 2:00 to complete.

Sunken Remnant (Map GI): The underwater remains of a mystical palace. The glowing ley lines and the palace treasure somehow remain intact. Expect sharp turns and the possibility of off-road. This course should take around 1:30 to 1:50 to complete.

Harmony Villa (Map GJ): A peaceful villa with a well kept landscape. The only catch is that the buildings and landscape have no regards for proper direction. Due to the dream-like nature of the landscape, reverse gravity is needed for the most effective traversal. This course should take 1:50 – 2:00 to complete.

Fetid Citadel (Map GK): An otherworldly transition to the waking nightmare. Traverse a factory which seems to exist only to spread toxins to a faltering realm. This course should take around 2:05 to 2:30 to complete.

The Wanderer Cup is a set of course about tackling and overcoming the difficulties of reality despite visions of overwhelming hopelessness. This cup is intentionally more difficult than the Stargazer Cup while being more grounded in terms of gimmicks.
Forsaken Bog (MAPGL): A damp bog untouched by society and left to grow. The wide roads and offroad buffers make the stage easy to compete in. The only thing to look forward to is maddening hymn of the bog and eternal darkness if you fall off, however. This course should take 1:30 to 2:00 to complete.

Mundane Purification Zone (MAPGM): A water purification plant and adjoining dam. The calming stillness of the course contrasts with the wild turns it offers. This course should take 1:45 to 2:05 to complete.

Motherlode Canyon (MAPGN): A crystal mine inside a massive canyon. Lattice supports help to bridge the void. This course should take 1:50 to 2:20 to complete.

Evaluation Summit (MAPGO): Race along mountainside roads sectioned off for a karting event. This is a test of Kart Racing skills with no gimmicks to worry about. This course should take 2:00 to 2:30 to complete.

Malicious Metropolis (MAPGP): A perception of society that is nothing but sky high office spaces. Despite working hard and following orders, personal progress is never made. Will you reach out to the truth or succumb to this hopeless depiction of reality? This course should take 2:00 to 2:40 to complete.

The Ascension Cup Is a set of courses about abandoning preconceived notions of which limit oneself to embrace the wild realities born from attempting to reach a higher plane of existence. The difficulty of this cup will wildly vary as well as its theming.
Futuristic Boardwalk (MAPZG): Fun still exists with progression. Take a nice drive in this advanced beach town! Do mind the merry-go-round and tight corners, however. This course should take 1:40 to 2:10 to complete.

Forbidden Monolith(MAPZJ): An average archaeological dig in a canyon has uncovered fantastic ruins! Even though the inhabitants have long since passed, their achievements still breath radiant life in the night sky. This course should take 2:30 to 3:15 to complete.

Flesh Paradise (MAPZK): An ever-expanding flesh castle born from the failures and self-destructive desires of all living beings. The castle and surrounding area appears as a dream fulfilling paradise free from the woes of the outside to the weak-willed and hopeless. The stronger willed will see its true form as a slow growing apocalypse bent on enveloping all living creatures into its fold. Regardless of appearances, all will meet the same fate. This 2 lap track should take 2:00 to 2:30 to complete.

Because of the body horror aspects of this stage KL_Abs-ParadiseIllusion has been added as a supplemental upload. This script will replace all flesh textures and disable all dynamic slopes in the stage. Use the NetVar paradiseillusion to toggle the look of the stage. The encore mode will be the opposite form of the default, rather than a color remapping. Make sure to load this script after abstraction pack for the proper thumbnail and encore palette!

Flesh Eden (MAP ZL)
: Atop Flesh Paradise is a mutated flesh mage with a SPB core lodged inside of her. She wants to spread her magical flesh over the world to cease the ills and burdens all life faces. She will stop at nothing to achieve this goal, going as far as to use her "Ascended" humans to stop you. Defeat her quickly to save the world! The boss can take about 1:50 - 2:10 to defeat with perfect execution. You have a hard limit of 4:30, where not even the defeat of the flesh mage will stop the spread of Flesh Paradise. On failure the stage will exit.

Map Hell
Cosmic Rift Classic (MAP ZM)
: A much more direct translation of the stage which inspired Cosmic Rift. The original circuit stage was modified to include slopes and be more compatible with Kart. Most set-pieces are close to their original location. While this stage shares the theme of Cosmic Rift the road is wider and there is space debris to wall you off from the vacuum of space. This 5-lap course should take 1:35 to 2:00 to complete.

All tracks retain their names from their parent releases.

Overgrown Castle is based off a map made for SUGOI.

Midnight Caves is based off of an entry for SRB2’s 2014 May/June Official Level Design Contest.

Empty Sanctum is based off a NiGHTS map made for SUBARASHII. Flats and textures for this course are taken from the FreeDoom Texture Pack for SRB2

Bio Satellite is based off of Bio Satellite and Egg Lasershow from KIMOKAWAIII. This map was first one made and inspired the rest of the cup when I realized that some elements copied from the source levels would make for good track elements when slightly modified.

Cosmic Rift is based off a circuit map made for SRB2 v1.90.4. An update for the map was made for SRB2 v2.0, but never released due to waning interest in the circuit game type.

Ethereal Crystal is an original track inspired by Noaru Valley, from the PlayStation 1 RPG Legend of Legaia. The map was made much more colorful and landmasses other than hexagonal crystal were added to make the track interesting and better to play on.

Sublime Bastion, Sunken Remnant, Futuristic Boardwalk Zone,Forbidden Monolith Zone and Mundane Purification Zone are original levels.

Harmony Villa takes inspiration from Mystic Forest and Soft Museum from NiGHTS into Dreams.

Fetid Citadel takes inspiration from the levels in the Dreamweaver’s World and Gnasty Gnorc’s stage from Spyro the Dragon. Elements from Dark Passage are the most prevalent.

Forsaken Bog is based off of D00D64’s GALF LEGACY and zxyspku’s Angel Arrow Zone’s design philosophies. The theming is original.

Motherlode Canyon is based off a rushed and oversized entry for SRB2’s 2015 March-June Contest. The stage offered things like rope hangs and polyobjects, but other gimmicks like a Metal Sonic Race available on not dying once before a certain point, door puzzles, and alternate paths were dummied out before release. The original Motherlode Canyon was much more of an Arid Canyon knockoff. I wanted this variant to standout compared to ACZ and Canyon Rush.

Evaluation Summit is an original level. The name is coincidentally synonymous with Trial Mountain from the Gran Turismo series.

Malicious Metropolis takes inspiration from Magatsu Inaba from Persona 4. Several design cues were taken from Lat''s Midnight Channel and Mayonaka Mk.II tracks. The skybox used in this stage is free to use and modify, as long as credit is given.

Flesh Paradise was intended to be the last track of the Wanderer Cup back when the cup's theme was feelings of hopelessness brought on by failure leading to self-destructive escape. The theming of the cup has changed to a more optimistic exploring and facing the difficulties/potential the real world has to offer. Forsaken Bog and Malicious Metropolis are remnants of the more negative cup theming.

Flesh Eden was intended to be the "Final Boss" of Abstraction Pack. It was intended to be the HELL MAP of the Wanderer Cup, with Flesh Paradise serving as the final level of the Wanderer Cup when Evaluation Summit was not planned for the cup. Flesh Eden is the name of the location, rather than the flesh mage being named Eden. The seraphic gate is independent of Flesh Eden and Flesh Paradise. Perhaps it will serve a greater purpose in the future?

  • Added Forbidden Monolith to the Ascension Cup. Because of this Flesh Paradise and Futuristic Boardwalk Zone are no longer extra maps. They are The new cup's FINAL and 1st track, respectively.
Forsaken Bog:
  • The bog is a touch more forgiving.
  • Removed a fence and widened the road near before the final stretch of road. It was doing more harm than good.
  • Some of trees in the skybox now properly meet in OpenGL.
  • Fixed the sides of the starting log rendering improperly in OpenGL.
Evaluation Summit:
  • Prevented a cheeky shortcut.
  • Thickened the finish line.
Malicious Metropolis:
  • Thickened the finish line to prevent phasing past it at speed.
  • Added some contrasting textures to the final stretch of pavement to make the cliffs less blind.
  • Fixed a missing texture.
Flesh Eden:
  • The Seraphic Gate's glorious wings will now properly render in OpenGL.
  • The boss now exits the level on failure rather than restarting for server stability/netgame environment.
Flesh Paradise:
  • Removed dripping water in the meat mode of the stage as they were causing desyncs for midgame joiners.
  • Fixed regal walls near the start of the map.
  • Altered respawns in the moving meat tunnel so a player will not spawn from the ceiling.
Flesh Eden:
  • Changed the stage from 0 to 1 lap. This will resolve crashes and unintended behavior with mods which use lap count such as Daytona Mod and TSR. The boss is is exactly the same.
  • Changed prompts from csay to cecho, to remove console warnings.
  • The boss intro will now play for everyone on the map.
  • Flesh Paradise has been added. When a new cup, tentatively named the Ascension Cup, gets released it and Futuristic Boardwalk will be added to it.
  • Because of the body horror aspects of Flesh Paradise KL_Abs-ParadiseIllusion has been added as a supplemental upload. This script will replace all flesh textures and disable all dynamic slopes in the stage. Use the NetVar paradiseillusion to toggle the look of the stage. The encore mode will be the opposite form of the default, rather than a color remapping.
  • As a bit of housekeeping: I am fine with external SOCs/Mods which modify/send to hell/banish my maps or otherwise change them, as long as the base mod is not touched. You accept any and all consequences if you modify my mod in such a manner.

Cosmic Rift:
  • Thrown items such as orbinauts and jawz should no longer phase through the road.
Sublime Bastion:
  • Fixed an incorrectly set death pit
Flesh Eden:
  • Fixed the stage not restarting properly on failure.
  • Added a Record Attack ghost.

  • Moved the map slots of the extra maps to an unused slot range to prevent conflicts with SFA Simple Map 1 and Ivo Industries. This should also prevent potential future conflicts with Ivo Industries. This will also serve for futureproofing for the levels yet to be added.
  • Futuristic Boardwalk moved from U0 to ZG.
  • Motherlode Canyon moved from U1 to ZH. It will move back to GN at some point in the future.
  • Flesh Eden moved from U5 to ZL.
  • Cosmic Rift Classic moved from U7 to ZM.
  • Motherlode Canyon had its waypoints parameterized for potentially better tracking.
  • Futuristic Boardwalk had a texture issue with the glowing hexagon texture fixed. The game would crash if you loaded Slipgate Cup V1.3 before Abstraction Pack.
Flesh Eden:
  • Fixed the boss crashing dedicated servers on defeat.
  • Paths were slightly adjusted so that Kartmp's "Hard Sneakers" is now compatible with the boss
  • A portal opens at the seraphic gate to give a rough estimate for how long a path is open.
  • Path 3 should no longer randomly dissapear if path 3 is picked again on the last hit.
  • Some walls were added to the blind turns.
  • Changed the thing number of the thunder shield spawner from 2278 to 3339 to prevent conflicts with Wind Tunnel's Quad Damage.
  • Removed redundant sign states and declarations.
Futuristic Boardwalk:
  • Changed the normally solid hexagon fence texture to something shorter, to indicate that it can be passed through.
  • Futuristic Boardwalk Zone has been added as Abstraction Pack EXTRA. If a new cup is made it will be added to that new cup.
  • Cosmic Rift Classic was moved from MAPGU to MAPU7. Its map slot was chosen at a time where I thought I would fill most of the Gs and not for continuity reasons.
Mundane Purification Zone:
  • The supports holding the platform near the start of the map were reduced in size.
  • Walls were added to the narrow walkways before the sloped U-Turn
  • Timers were added to the alternating sloped platforms.
  • The polyobjects were have a slightly smaller span.
Evaluation Summit:
  • A minor checkpoint issue was resolved.
Motherlode Canyon:
  • Some glass was made solid.
  • Death planes were added/modified in several tracks to prevent exploits. This affects Forsaken Bog, Mundane Purification Zone, Motherlode Canyon, and Harmony Villa.
Cosmic Rift:
  • The shortcut is now properly blocked so it is absolutely not possible to do with a perfect boost on the first lap.
  • The shortcut now properly opens when the first player starts lap 2 rather than when everyone starts lap 2.
Fetid Citadel:
  • An unintentional shortcut has now been made official via firewall.
Motherlode Canyon:
  • Mine carts should no longer take you outside the planes of reality.
  • A set of rocks can no longer be used for a highly unlikely shortcut.
  • You should now properly “exit” the track even if a SPB hits you.

  • 4 New Maps: Forsaken Bog, Mundane Purification Zone, Motherlode Canyon, and Evaluation Summit have been added as the Wanderer Cup. They do have encore changes and staff replays.
  • Several Time attack records have been updated and improved upon.
  • Malicious Metropolis has moved from Dreamweaver Cup Bonus to Wanderer Cup Final.
    All maps after Ethereal Crystal have moved one slot down to prevent conflicts with minenice’s battle map The Reef .

Harmony Villa:
  • It is now “possible” to dodge the SPB on the blue U-turn. I would still recommend going the normal path if one is after you, however.
  • Added more fencing at the start.
Cosmic Rift:
  • Unnerfed the shortcut. It is still impossible to do with a perfect start.
  • Reduced the steepness of the steep slope. It is still possible to skip it entirely.

Malicious Metropolis:
  • The majority of MC Roaming Shadows have been replaced with Malicious Metropolis Roaming Shadows. They move the same but have a much smaller hit box and only spin you out on collision.
  • Added Arrows and glowing midtextures to the sneaker panels near the start of the track.
  • Added an item set to the first park shortcut.
  • Made the second park shortcut more difficult to do sneakerless and buffed the other paths.

  • Malicious Metropolis has been added as MAPGK as a Dreamweaver Cup Bonus map. If a new cup gets made it will move to that new cup.
  • I’ve noticed from general feedback that a majority of stages in this pack are unsuitable for netgames either due to track quality, or difficulty. As such, AbstractReduction.soc was made to move these stages to MAP HELL and package the remaining stages into the Abstraction Cup. The stages that are in the Abstraction Cup are: Sublime Bastion, Sunken Remnant, Malicious Metropolis, and Cosmic Rift. This SOC has no reflection on how I feel about the stages.
Overgrown Castle:
  • Added boosters if you fall off the diamond shaped road.
  • Changed the end of lap shortcut to improve consistency.
Empty Sanctum:
  • Added boosters to the outer edge of the sloped cavern area.
Bio Satellite:
  • All attack lasers have been changed to translucent FoFs, to make the stage more accessible to those who have epilepsy or are sensitive to flashing lights. The only laser which remains is the one in Egg Lasershow’s arena, which is subject to change.
  • The first shortcut is less punishing if you get knocked into it without a boost item.
Cosmic Rift:
  • The shortcut at the start has been nerfed. It now saves 2-5 seconds, down from 10 seconds.
  • Occ-san-geen was modified to remove the ~15 seconds of silence at the end of the song.
  • Death planes were redone in the middle section. This should make death more reasonable.
  • The bright green drift indicator on the steep U-Turn no longer has physics. This makes dodging the SPB and the approach of the U-Turn much easier.
Ethereal Crystal:
  • The circuit finish line no longer extends to the ceiling; work harder for your shortcut. It may get removed in a future patch.
Sublime Bastion:
  • Added 3 more items per item set to accommodate for the wide road.
  • A lap can now be completed with shrink.
Sunken Remnant:
  • Added a (slightly hidden) alternate means to reach the sandy area with sneaker panels.
  • The middle path near the end of the lap no longer has invisible springs. They were a remnant from before the stage was sunken.
Harmony Villa:
  • Added glass and moved items closer to the center in the mirror room.
  • Added some fencing; some fencing is left open to ensure you can get back on track if you get knocked out.
  • Added boosters to the normal gravity section at the start of the second lap. This path is still inferior by about 10 seconds during a race. I will have to find a better means to balance the paths in a future patch.
Fetid Citadel
  • Added some signs.
  • Added midtextures to some areas to indicate unsafe drops.
  • Death planes that could be unintentionally hit from underneath have been made solid on the underside to prevent this. This affects Sublime Bastion and Midnight Caves.
Empty Sanctum:
  • Adjusted a small step near the start of the course to prevent bumping into it.
  • Fixed (again) a soft-lock in the sloped cave area.
Bio Satellite:
  • Adjusted the skybox. It looks about the same in both rendering modes, but it will no longer cause frame rate drops on weaker machines or on higher resolutions.
  • Added a fence.
Cosmic Rift:
  • Adjusted the glue near the start of the race. It is now less punishing if a player drives into the first half of it without a boost item.
Sunken Remnant:
  • Properly added giant bubbles to indicate the downwards current (Thing type 2220)
Harmony Villa:
  • Added some blocking to the start of the race. It is still possible to drive back on course if you get knocked out of bounds.
  • Fixed a gravity issue near the end of the lap.
  • Added a barrier in the forest area to prevent being knocked out of reverse gravity.
  • MAPGU – Cosmic Rift Classic was introduced as a Hell map in the last patch. Try it out if you haven’t already.
  • Improved all RA times for the Stargazer Cup.
Overgrown Castle:
  • Added a shortcut.
  • Added a tree on the upwards spiral to reduce the chance of going down it.
Midnight Caves:
  • Removed an exploit.
  • Added a shortcut.
Empty Sanctum.
  • Redid the starting room of the map for easier navigation.
  • Connected the ramp near the first item set to the upwards waterfall spiral.
  • Extended the distance between the U-turn and straightaways to allow for better turn anticipation.
Bio Satellite:
  • Added decoration.
  • Replaced the S-turn after the corkscrew with a straightaway.
  • Moved the first item halfway up the laser lanes. The challenge should be the lasers, not opponents.
Cosmic Rift:
  • The entire map now has players at 93% of the normal size. This will make the track easier at the expense of making it ~10 seconds longer.
  • Added arrows and a subtle drift marker to the steep slope.
  • Added a shortcut marker near the start of the map.
Ethereal Crystal:
  • Extended the finish line boundary.
Sunken Remnant:
  • Added bubbles.
  • The downwards current near the end of the map should be more hazardous.
Fetid Citadel:
  • Adjusted midtexture decals to reduce Z-fighting in OpenGL.
  • Each map has now been tested with grow. Of them, Fetid Citadel and Empty Sanctum had issues preventing lap completion. These issues are now resolved.
Midnight Caves:
  • The fences which were added last update are now actually solid.
  • Orbinauts can now climb a rock bridge onto a stump.
Cosmic Rift:
  • The song credit has been updated. The full details of the song credit change are in the MAINCFG.
  • A death plane has been adjusted.
  • Cosmic Rift has been added to Map HELL.
Ethereal Crystal:
  • The map is flatter overall. While the change is cosmetic only, it should help alleviate some issues with blind turns.
Harmony Villa:
  • The spawning boosters should now work properly. They will now spawn 2 seconds after first place starts lap 2 rather than 2 seconds after everyone finishing lap 1.
  • Miscellaneous graphical fixes and additions and OpenGL optimizations have been made to most levels.
  • End Signs were added to all of the Dreamweaver Cup.
  • Cup ends now lead to EVALUATION.
Empty Sanctum:
  • Spawn traps in the upwards waterfall section were resolved.
Cosmic Rift:
  • A death pit near the banked turn has been lowered.
  • You can no longer skip the tall slope by going underneath the adjacent platform. Here is some advice if you experience difficulty at that section: when you start to slowdown after the boost, begin drifting or drift near the end of the sneaker panels. With great skill you can skip the slope entirely by slip-tiding on the sneaker panels.
Harmony Villa:
  • Thrown items now work as expected in reverse gravity.
  • Sneaker panels will spawn after the first lap in the normal gravity section. It is still slower than staying in reverse gravity, however.
Fetid Citadel:
  • Reduced and denoted glue.
  • 4 new maps: Sublime Bastion, Sunken Remnant, Harmony Villa, and Fetid Citadel have been added. They do have encore changes and staff replays.
  • Ethereal Crystal has moved from Stargazer Cup BONUS to Dreamweaver Cup 1.
  • Because of the large update the Stargazer Cup is now part of the Abstraction Pack.
Overgrown Castle.
  • The level’s music has increased in volume after converting it to .ogg. If there is a way to increase the in-game volume of .spc files, please let me know.
  • Star posts have been added to the beginning and end of the path split.
Empty Sanctum:
  • The barriers on the edges of the first waterfall cavern have been made more consistent. The best way to approach it is still to take a sharp turn by drifting in midair.
  • The sloped outdoor U-turn now has a buffer of off-road before the pit.
  • The pillars near the end of the track have been adjusted so that drift timings are less tight.
Bio Satellite:
  • The warning signs at the start have been made twice as wide.
  • Reduced glue.
  • The corkscrew shortcut should now be possible for most weight classes. With vanilla characters, Knuckles will be able to execute it perfectly, Tails and Eggman will undershoot it, Sonic and Metal Sonic may hit the wall and plummet or with much more precise timing execute it perfectly. Metal Sonic can also overshoot it.
  • The ramp after the corkscrew has been adjusted for more success after respawning.
Cosmic Rift:
  • Spawn traps near the end of the track have been fixed.
  • A low wall has been added to the first hairpin of the track.
Ethereal Crystal:
  • Thickened the death barrier near the half-pipe.
  • A new track, Ethereal Crystal has been added as the Cup’s bonus track. If I make another cup or a large map pack, this track will move to another cup.
  • Devtimes in record attack have improved somewhat. Thanks to the dedicated speed runners and people who are able to beat me in net-games for showing me how to play my maps better!
  • Checkpoint issues in Midnight Caves, Empty Sanctum, Bio Satellite, and Cosmic Rift have been resolved.
  • The Cup is no longer in beta.
Overgrown Castle:
  • An alternate path has been made more accessible.
  • Flags and other decorations have been added.
  • The level select picture has been updated.
Midnight caves:
  • The arrow signs are now 4 times as large.
  • Rocks have been added to the end of first turn.
  • Minor details have been added.
Empty Sanctum:
  • You are less likely to be wedged in the end of the half pipe turn.
Bio Satellite:
  • A set of yellow springs have been replaced with a ramp.
  • The corkscrew shortcut is more difficult to execute.
  • The S-turn had its first half revamped and should be less awkward to navigate.
Cosmic rift:
  • The hairpin turn shortcut is no longer possible with a perfect start.
  • The upward turn is now a banked slope for better visibility.
  • More planetoids have been added.
  • All tracks now have encore pallets.
  • Dev times are now included. They are meant to be expert level and there aren’t any medals for beating them.
Cosmic Rift:
  • A turn and booster have been adjusted.
  • Immediate desyncs when replaying ghosts has been fixed.
  • The course is now 3 laps.
Overgrown Castle:
  • The mini-map has been updated.

Bio Satellite:
  • The mini-map has been updated.
  • It should no longer be possible to repeatedly spawn over a pit by going under a bridge.

Cosmic Rift:
  • The mini-map has been enlarged and updated.
  • Several steep slopes and tight turns have been alleviated.
  • Some course skips have been removed.
  • The course is somewhat more detailed.
  • The cup is now compressed via PK3.
  • Song credits are now added.
  • Slope physics have been removed from some unneeded areas.
  • Arrows have been added in some more areas.

Overgrown Castle:
  • The course is somewhat more detailed.

Midnight Caves:
  • Fencing and advance warning is now given for the sharp waterfall turn.
  • The waterfall at that sharp turn no longer has current.
  • The fence texture has changed to better contrast with the environment.

Empty Sanctum:
  • The course is more detailed.
  • The map has been changed to reflect closed gaps.
  • The start of the map should have better visibility.
  • The sloped U-Turn has been flattened and replaced with a staircase.
  • The first waterfall cavern now has barriers on the outer edge of the platforms.
  • The sloped outdoor U-Turn is much smoother.
  • The second waterfall cavern has had a gap bridged and (hopefully) a spawn trap has been removed.
  • A sky conflict (notably with Adventure Acre Zone) has been resolved.

Bio Satellite:
  • Laser timings have been made fairer.
  • It should no longer be possible to die on the first straightaway of the course. A barrier was added to the outer edge and if you spin out, you will reach the top of the incline with no further damage.
  • The end of the second straightaway now has some extra ground to drive on if you were unable to avoid the end via the turns or the middle path.
  • The corkscrew now has some added arrows.
  • The S-turn is much more lenient. It is now less steep; glass barriers have been added to the inside edges and most of the springs bridging the curves have been removed.

Cosmic Rift:
  • Spawn traps have hopefully been reduced.
  • Some checkpoint skips were resolved.
  • The first steep slope no longer has a checkpoint.

Rating this with 5 stars seems a bit counterintuitive, considering that for the wide arrange of maps this pack has, quality can vary significantly, especially in the older maps. That said, this deserves it, and there are many reasons for it:

This pack (as of v3.7a) contains 19 race maps (+1 Hell Map) and a boss fight (the only boss fight ever created in Kart for the time being). True to its name, the theming of these tracks can best be described as "Abstract", going from more traditional settings like a castle or a level in Sonic Adventure, to incredibly bizarre places like a cleaning facility topped by OFF music and a dimension full of meat, flesh and bodily fluids... And apples.

The earlier maps are among the first custom maps to be released for Kart and they show their age. Despite this, they are still serviceable at worst, and at best, in the case of Cosmic Rift, have become infamous as the true "Rainbow Road" of Kart due to the extreme slopes, lack of barriers and overall difficulty, combined with the constant sneaker panels that, even though they may break racing balance, add to the charm of it all.

Theming and layout go together a long way and achieve that each track, for better or worse, remains unique each time. Personal favorites are the aforementioned Cosmic Rift and Motherlode Canyon, an alternative to the vanilla Canyon Rush that I personally prefer. Regardless, all tracks manage to make themselves feel different from each other and this pack will barely ever feel monotone.

The biggest attraction in this pack is the use of lua for tracks like Flesh Paradise, perhaps the first horror-themed track in Kart, and its boss fight relative, Flesh Eden. The mapper has managed to create a challenge to beat cooperatively thanks to lua, and although it's hidden behind Map Hell, it's worth trying at least once.

Overall, this isn't the best map pack when it comes to pure visuals or layout perfection. But it manages to create a niche and make for one of the most creative settings of any Kart tracks in the whole game, and that, plus the constant growing experience of the author and incredible ambition and use of lua in them, make this pack a must have for any server looking to fill their repertoire with custom tracks quickly.

While some maps (especially the earlier ones) can feel a bit awkward to navigate, and the visuals are somewhat limited by vanilla textures - I don't think any other map pack goes to such lengths to experiment and incorporate interesting mechanics.
The technical side to these maps are second to none, Chao uses every tool available to really push what's doable in kart. If you're more into the mapping side of things, this pack should definitely be experienced.
On the racing side, certain maps can initially be a bit painful for newer players, but for me the appeal of Abstraction pack is you'll rarely come across just a bog-standard race track. There's always an idea or concept being explored, which helps make this pack stand out.
And there's even lore behind the different cups/maps! And a boss battle!

Chaobrother is one of the most dedicated and hardworking map makers I've ever seen, to a fault. It really, really shows in Abstraction Pack. Many of these maps, like Bio Satellite and Flesh Paradise go for grand scale, and complicated to set up gimmicks with a simple and effective end result.

The crown jewel of this pack is definitely Flesh Paradise, as it encapsulates the work Chaobrother puts into all his other maps; it uses every technique of his in tandem to make something truly special.

Some maps suffer from readability issues and the dreaded Double Step-Up Stairs, which results in hilarious situations where you can go up a stair, but the orbinaut you just shot in front of you rebounds off the side of it and hits you (Seriously Chaobrother just making more stairs that are half as high each would fix this instantly).

The maps in this pack vary wildly in difficulty, which is often a good thing, but is a little strange here because of the huge leaps. The best example is probably Cosmic Rift, a map many people endearingly describe as "The Rainbow Road of SRB2Kart". It's bitterly hard, and fights the camera extremely hard to the point where it's difficult to see where the turns end and the endless abyss begins. It's a huge difficulty spike in an otherwise pretty accessible map pack.

Despite that, Abstraction Pack is easily one of the most interesting and just downright impressive map packs out there. Definitely give this one a try by yourself or with your friends.

Some of these maps can feel pretty awkward to drive on, with some odd formations of land, or directioning issues, but the sheer outer worldly absurdity of some of these maps is truly a sight to behold. And if you got the nerves for it, Flesh Paradise... damn.
